Discussion about Dungeon (Dark Elves).

Forget about summoning a Letos; it's useless for him, like an umbrella for a fish. Chaos is much better for him, with more powerful spells, attack, and magic. An Orcish Assassin is ready...

But that's a hasty judgment. I remember fighting against Haghesh with Letos, and throughout the battle, Phoenixes with Shield and Vampirism, and Wolf Riders with Subjugation did all the work. It was a full-fledged Dark faction – he picked up creatures from Treasure Rooms and Utopias (the map was large and rich).
When we played the rematch, the opponent took Vaishan against Haghesh and went for a spellcaster duel. At his 29th level, he only had 22 spell points due to my "Strength against Magic" perk. And we also need to subtract 25% from that due to Chaos Weakness... In general, the main damage was dealt by the troops, not magic.
Against an Orc, a Warlock spellcaster is really effective because an attack or spell removes the Shield of Fury, and then the chains go through the "naked" stack.
300+ Minotaurs took down 4 Cyclops with the first attack, took some damage in return, after which they were reduced to 181, and with the second attack, they eliminated 41. Matriarchs also took down 400+ Warmongers with a single shot... However, it was impossible to win that battle with just an army. If it had been a Dark faction, I would have lost. Or, if I had a second school of magic, there are some fun spells there...
